CROSS REFERENCE TO RELATED APPLICATION(S)

This application claims the benefit of priority from U.S. ProvisionalPatent Application No. 63/204,558, filed Oct. 8, 2020, which isincorporated herein by reference in its entirety.

Botanical classification: Dracaena sansevieria.

Varietal denomination: ‘OSV Sans 015’.

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct variety ofSansevieria plant, botanically known as Dracaena sansevieria, having thevarietal name of ‘OSV Sans 015’ and commercially referred to as “MistyStar”. ‘OSV Sans 015’ is the result of a cross conducted in Costa Ricain a planned breeding program by the inventor. The new variety wasselected and first asexually reproduced by cuttings in Costa Rica. ‘OSVSans 015’ has been trial and field tested and has been found to retainits distinctive characteristics and remain true to type throughsuccessive propagations. The present invention has not been evaluatedunder all possible environmental conditions. The phenotype may vary withvariations in environment without a change in the genotype of the plant.

When compared to Sansevieria variety named ‘OSV Sans 013’ (U.S. Plantpatent application Ser. No. ______), the new variety exhibits a similarrosette leaf formation with leaves having horizontally stacked lines.However, ‘OSV Sans 015’ differs from ‘OSV Sans 013’ in having lightgreenish yellow to white colored margins and the random presence offaded green, vertical lines. Further, the following characteristicsdistinguish ‘OSV Sans 015’ from other Sansevieria varieties known to thebreeder:

-   -   Rosette leaf formation;    -   Leaves grow upward and then arch outward;    -   Horizontally stacked and static lines are present across leaves;        and    -   Faded green, vertical lines are randomly present along leaves.

DESCRIPTION OF THE DRAWING

The accompanying photographic drawing taken at approximately 18 weeks ofage illustrates the new variety, with the colors being as nearly true asis possible with color illustrations of this type.

DESCRIPTION OF THE PLANT

The following detailed description sets forth the characteristics of thenew variety at approximately 2 years of age. The data which definesthese characteristics was collected in a greenhouse in September of 2021in Winter Garden, Fla. Plants of the new variety were grown under 2,000foot candles of artificial light in 15 cm pots in a climate-controlledgreenhouse in Winter Garden, Fla. having 86% relative humidity and anaverage temperature of 28° C. Color references are primarily to theMunsell Plant Tissue Color Book, 2019 publication, except where generalcolor terms are used.
